IMPROVEMENT IN LAM P-BURNERS.

Specification forming part of Letters Patent No. I 84,245.. datedNovember 14, 1876; application iiled April 28, 1876.,

To all whom it may concern Be it known that I, EvANs H. JENKrNs, oDayton, in the county ot' Montgomery and State of Ohio, have inventedcertain new and useful Improvements in Lamp-Burners; and I do herebydeclare the following to be a full, clear, and exact description of thesame.

This invention has in View the production of a' burner for coal-oillamps so constructed that the wick, held in the throat with ayieldingpressure, will not clog, and so arranged that an air-passage isprovided at the side of the wick to allow the escape of generated gasesand the ingress of air.

My improvement consists in in the particular formati-on of the throatand the combination therewith of a spring division-plate so arrangedthat on one side it bears against the wick and on the other forms anair-passage into the lamp.

To enable others skilled in the art to which 1ny invention appertains tomake and use the saine, I would thus proceed to describe it, referringth roughoutto the accompanying draw-` ings, in which- Figure l is afront elevation of my improved burner. Fig. 2 is a side elevation ot'the same taken in section of-Fig. l. Fig. 3 is a sectional bottom vieWof the throat and Wiekraising pinions.

Corresponding letters of reference indicate like parts in all ot' thefigures.

A represents the throat otthe burner, which differs only fromthcordinary throats in that :it is somewhat thicker from side to side,

except at the top, which on one side is cut at '4 the corners, bent in,as represented, and held by the side pieces a, which form' lips to holdthe bent portion in place. B represents a thin strip ot' brass or othermetal ot' the same Width as the interior ot' the throat, which is fittedinto it by having its bent bottom edge c, Fig. 3, inserted in atransverse slot at the bottom of one side of the throat. This preventsthe strip from being displaced, and at the same time it is provided withoritlces or air-passages d. At the 'top the strip rests against thebent-in portion of the .throat at e, Fig. 2, and near the bottom itbears against the wick-pinions O, which are arranged in the usual mannerin the cap D, as represented. At the top of one side of the throat, justbeneath the bend f, are a row of perforations, g, openin g into theair-passage behind the strip B. Instead of perforations the side of thethroat might be cut transversely and the portion below the cut bent into form an aperture.

The advantages of this arrangement of parts are, that the Wick is notliable to clog owing to irregularities in its thickness or the presenceof charred portions that may have adhered to the side of the wick andbecome lodged in the throat, and at the same time an air-passage isformed to convey away the generated gases that frequently form on thesurface of the oil and render it liable to explode. The arrangement,too, of the aperturesg is such that charred paiiticles of the wickfalling from it cannot get into them. In order to'hold the edges ot' thewick at the top and prevent its spreading, the sides of the throat oneach side are cut away, leaving only -the edges h projecting from aneighth to a quarter of an inch. These edges serve to hold the wick abovethe point of ignition and to cause anV even and brilliant flame.

I ain aware that burners with spring division-plates have been vemployedbefore, and consequently make no broad claim to such plate. But- What Ido claim as new, and desire to se- 'cure by Letters Patent, is-

The hereindescribed lamp-burner, consisting of the cap D, throat A,having one side of its top bent in'and peri' cutaway, as described, thedivision-plate B, so arranged as to provide an air-passage on one sideot' it, and Wick-pinions C, the Whole constructed and connected in themanner and for the purpose specified.

Witness my hand this 26th day of April, A. D. 1876.
